On Port-Hamiltonian Formulation of Hysteretic Energy Storage Elements: The Backlash Case
This research develops a port-Hamiltonian framework for modeling hysteretic energy storage elements, specifically focusing on backlash systems where current depends on input history. The method uses a family of storage functions to incorporate hysteresis into structured energy-based models, successfully expressing the system as a port-Hamiltonian system with nonlinear dissipation.
